Effective insulation for internal walls

ProofTherm Internal wall insulating plaster is a 100% natural, breathable and easy to use insulating plaster that is suitable for use on most internal wall structures.

Its lightweight, breathable formulation makes ProofTherm an ideal base coat to be used prior to plastering with a standard internal finish plaster. It is particularly useful in upgrading the thermal insulation performance of older properties where maintaining breathability is essential in avoiding problems with mould and damp.

ProofTherm insulating plaster is an inert mineral product containing zero VOC’s. Advanced manufacturing and a unique formula have enabled us to create a high-performance, lightweight and breathable insulation solution for the 21st Century.
